Thalamic and cortical signals synergistically represent auditory prediction errors

The paper shows that thalamic and cortical signals work together to represent auditory prediction errors, with synergistic interactions that go beyond simple relay.

State-dependent top-down and bottom-up processes in gamma-band (~40 Hz) oscillations of the cat EEG

This study examines gamma-band oscillations in cat EEG during wakefulness and sleep, finding top-down directionality in quiet wakefulness and bottom-up responses to simple stimuli.

Differential Effects of Haloperidol on Neural Oscillations During Wakefulness and Sleep

This study examines how haloperidol affects oscillatory and aperiodic brain activity during wakefulness and sleep in cats, revealing state-dependent modulation of oscillatory dynamics.

Cortical high-frequency oscillations ({approx} 110 Hz) in cats are state-dependent and enhanced by a subanesthetic dose of ketamine

This study examines how subanesthetic ketamine affects high-frequency cortical oscillations in cats, finding state-dependent changes and respiratory coupling.

Ketamine and sleep modulate neural complexity dynamics in cats

This study examines how ketamine and sleep stages affect neural complexity in cats using Lempel-Ziv compression, finding dose-dependent changes and differences across brain regions.

Gamma band alterations and REM-like traits underpin the acute effect of the atypical psychedelic ibogaine

This study investigates the electrophysiological effects of ibogaine in rats, finding increased gamma oscillation power with reduced coherence and complexity, suggesting REM sleep traits in the psychedelic state.

Power and coherence in the EEG of the rat: impact of behavioral states, cortical area, lateralization and light/dark phases

The paper analyzes iEEG power and coherence in rats across behavioral states, cortical areas, and light/dark phases, finding state- and area-dependent changes and REM sleep-specific hemispheric differences.

Electrocortical temporal complexity during wakefulness and sleep: an updated account

This study shows that electrocortical temporal complexity decreases during sleep regardless of electrode configuration, suggesting brain-generated differences in complexity between wakefulness and sleep.

Decreased electrocortical temporal complexity distinguishes sleep from wakefulness

The paper uses permutation entropy to show that electrocortical complexity decreases during sleep compared to wakefulness in rats, suggesting a global thalamo-cortical pattern change.

Nasal respiration entrains neocortical long-range gamma coherence during wakefulness

This study shows nasal respiration entrains inter-cortical gamma coherence during wakefulness but not during sleep.
